OUTPUT MODULES

Output modules are the interface between the PLC and external output devices such as contactors, interposing relays, digital displays, indicator lamps, etc. Ther are may types of output modules, each of them with a differing output switching voltage specification and/or number of output points per module.

A single module can be obtain with up to 64 output points and the range of voltage that can be used is from 24VDC to 120/240VAC. Triac/SSR output modules are fast response and are available with a maximum switching current of 1A. Transistor output modules are available for either sink or source type output devices and can switch 12VDC and/or 24VDC.

TTL, CMOS output modules can be used to directly drive TTL or CMOS ICs with operating voltages between 4.5 and 15VDC.

Output modules are available for analog output, positioning modules, timers and counters.
